Agricultural seed planter
First Claim
1. A seed planter unit comprising:
- a frame having front and rear ends and defining a longitudinal axis of said planter which defines a travel direction therefore;
means, adjacent the front end, for attaching said planter to planter conveying means;
means for supporting said frame at a desired height above a surface of soil;
a shaft mounted to the frame, oriented at an acute angle to and transversely of the longitudinal axis;
soil groove cutting means, consisting of a plurality of circumferentially spaced individual groove forming tines extending away from the shaft and all lying substantially in a single plane normal to the shaft, supported by said shaft for free rotation about the axis of the shaft and positioned to interact with the soil, said acute angle being such that the tines of the soil groove cutting means will be rotated about said shaft axis by their interaction with the soil during forward motion of the planter in the direction of travel, all said groove forming tines being angled to extend, adjacent their ends, circumferentially in a direction opposite to the direction of said rotation of the soil groove cutting means to produce, during said forward motion of said planter in the direction of travel, a sequential plurality of discrete parallel open topped grooves in the surface of that soil, each said groove extending transversely of the direction of travel at an acute angle thereto; and
means attached to the frame for supplying seed to said open topped plurality of grooves subsequent to their formation.

Abstract
An agricultural seed planter comprising a frame adapted to be mounted to any conventionally drawn tool bar; a shaft attached to the frame and angled relative to the direction of travel and having mounted thereupon a soil cutting wheel designed as a multi-tined spider; sweepers attached to the frame and positioned to the side and parallel to the plane of rotation of the soil cutting wheel; a vertically adjustable ski shaped surface contacting member adjacent to the soil cutting wheel adapted so as to regulate the depth of soil cut; a seed dispensing apparatus positioned to deposit seed generally behind the soil cutting wheel and a suitable seed covering device, the sweepers comprise rigid formations attached at their forward facing ends to the frame of the planter and extend rearwards, on either side of an in close proximity to the multi-tined spider wheels such that, when in motion, any accumulated debris is swept from the tines of the spider. The seed dispensing apparatus being a chute having flexibly deformable skirts located to be in soil contact.
